Anisotropic refinement

Anisotropic refinement is included among the strategies for macromolecular refinement.

Analysis
PARVATI - Protein Anisotropic Refinement Validation and Analysis Tool. The PARVATI server accepts a PDB file containing ANISOU records or TLS records.

ANISOU records

 * The ANISOU records present the anisotropic temperature factors.
 * The anisotropic temperature factors (columns 29 - 70) are scaled by a factor of 10**4 (Angstroms**2) and are presented as integers.


 * The anisotropic temperature factors are stored in the same coordinate frame as the atomic coordinate records.


 * ANISOU values are listed only if they have been provided by the depositor. The depositor provides ANISOU records, PDB verifies their format.


 * The anisotropic temperature factors are related to the corresponding ATOM/HETATM isotropic temperature factors as B(eq), as described in the ATOM and HETATM sections.
